| 41. | The methods of signal processing include time domain, frequency domain, and complex frequency domain.
|
| 42. | One can check this easily in the frequency domain, where differentiation becomes multiplication by ?.
|
| 43. | Time domain methods are preferred to frequency domain methods when short-term recordings are investigated.
|
| 44. | :The sinc function in the time domain is a windowing function in the frequency domain.
|
| 45. | Signals are converted from time or space domain to the frequency domain usually through the Fourier transform.
|
| 46. | The most common purpose for analysis of signals in the frequency domain is analysis of signal properties.
|
| 47. | A low-pass lifter is similar to a low-pass filter in the frequency domain.
|
| 48. | In frequency domain, they are displayed as phase shift among the signals received by the sensors.
|
| 49. | In other words, convolution in the time domain is equivalent to multiplication in the frequency domain.
|
| 50. | In the frequency domain they may be named kernel, logon, and frame, among others.
